Add Mass Prefix

[vetty]

Hello,

I have 30 Sub-Forums and want to add atleast 50 Prefixes to each Sub-Forum,
which makes it to 1500 prefixes.
But I think It is only possible to add prefixes 'one by one'.

I have used a mod which makes it possible to add mass sub-forums.
Can similar mod be created to add "Mass Prefixes" ?

Thank you.
